Microplastic intake of Unio mancus Lamarck 1819 collected from Ataturk Dam Lake, Türkiye
AI summary Read the abstract
Researchers examined microplastic intake in the freshwater bivalve Unio mancus collected from Ataturk Dam Lake in Turkey, characterizing the size, shape, and polymer composition of microplastic particles and fibers ingested by the mussels. The study documented microplastic contamination in this dam lake population, contributing to understanding of freshwater bivalve exposure to plastic pollution in Turkish inland water systems.
MPs refer to plastic particles and fibers ranging in size from 1 µm to 5 mm, which can originate either from direct production (e.g., microbeads in personal care products) or the breakdown of larger plastics (e.g., microfibers from textiles, rubber abrasion particles) (Kurniawan et

The first evidence of microplastic uptake in natural freshwater mussel,Unio stevenianusfrom Karasu River, Turkey
AI summary Read the abstract
This brief report documents the presence of microplastics in a freshwater mussel species (Unio stevenianus) from the Karasu River in Turkey, providing first evidence of microplastic uptake in this native freshwater species. High microplastic concentrations in the mussel habitat indicate that the river is significantly polluted with plastic debris.
Tracking the microplastic pollution in the freshwater environments of southeastern Türkiye: Usage of Unio delicatus, Unio Terminalis and Dreissena polymorpha as bioindicators of microplastics
AI summary Read the abstract
This study examined microplastic contamination in three freshwater mussel species collected from rivers and a dam lake in southeastern Turkey, finding relatively low average concentrations (under 1 microplastic per individual) but confirming that these mussels do accumulate plastic particles from their surroundings. Because mussels are filter feeders with a fixed lifestyle, they reflect local pollution levels well, making them useful sentinels for tracking microplastic contamination in freshwater ecosystems. The research adds to growing evidence that microplastics are now present even in inland freshwater species far from the ocean.
The microplastic pattern in Turkish lakes: sediment and bivalve samples from Çıldır Lake, Almus Dam Lake, and Kartalkaya Dam Lake
AI summary Read the abstract
Researchers investigated microplastic contamination in sediments and bivalves from three Turkish lakes, finding 19-156 microplastics per kilogram in sediments and varying levels in different bivalve species, with fibers and fragments as dominant shapes.
The Use of Zebra Mussel (Dreissena polymorpha) as a Sentinel Species for the Microplastic Pollution of Freshwater: The Case of Beyhan Dam Lake, Turkey
AI summary Read the abstract
This study detected microplastics in zebra mussels from Beyhan Dam Lake in Turkey, finding an average of several particles per individual with fibers predominating, providing the first evidence of microplastic pollution in this freshwater bivalve species from Turkish inland waters.
Distribution of environmental microplastics in different tissues of indigenous freshwater bivalves (Unio spp.): a case study from the Sejenane River in Northern Tunisia
AI summary Read the abstract
Researchers examined microplastic contamination in three species of freshwater mussels from a river in Northern Tunisia, analyzing particles in gill and digestive gland tissues. They found microplastics present in all species, suggesting these filter-feeding bivalves accumulate particles from their environment. The study demonstrates that freshwater mussels can serve as effective biological indicators for monitoring microplastic pollution in river ecosystems.
